Hydraulic bedplate threaded locking pin step pressing plate zinc base glass test rack

Abstract

The invention relates to a tempered glass test checking rack, in particular to a hydraulic bedplate threaded locking pin step pressing plate zinc base glass test rack. The invention is characterized in that a broken gap is formed in the upper plane of a rear plate; a supporting baseplate is fixed at the lower end of the broken gap; the center of the lower plane of the rear end of a test bedplate is provided with a T-shaped guide rail; a hydraulic elevator mechanism is arranged between the T-shaped guide rail and the supporting baseplate; the upper plane of a supporting side plate on one side is provided with an impact stand column on which an impact cross rod is rotatably fixed; a height positioning ring is fixed on the impact stand column in a liftable way, and supports the impact cross rod; an air cylinder impactor is slidably fixed on the impact cross rod, and is applied to realize consistent severity during hammering each time and thus ensure the unification of breaking test standardization and unification; a rack front middle pull rod, a rack front upper pull rod and a rack rear upper pull rod together fix a broken glass recycling container; a step rail pressing plate assembly is fixed on the upper plane of the test bedplate, thus realizing continuous and random adjustment on tempered glass plates of different sizes.

Description

technical field [0001] The present invention relates to a tempered glass test and inspection frame, in particular to a zinc-based glass testing machine with a hydraulic platen, threaded locking pin, stepped platen, pressure plate, which can be enlarged or reduced around the pressure plate, and uses a reversible workbench to test the performance index of the glass. shelf. Background technique [0002] Fragmentation test is a main way to detect the quality of tempered glass. According to the requirements of national standards, after the 3mm thick tempered glass is broken, the fragments in any 50*50mm should be more than 30 pieces, and the 4mm~12mm thick tempered glass is broken. Fragments within any 50*50mm should be larger than 40 pieces, and a small amount of long fragments are allowed, the length of which should not exceed 75mm. The direction of the strip-shaped fragments should be roughly parallel to the edge of the glass. If they are not parallel, the included angle sh...

Problems solved by technology

This method is not only inconvenient to operate, it takes a long time, and the tape is a disposable product, which is easy to cause waste and pollution, and the tape residue on the test bench must be removed after each test to remove the broken glass, otherwise , the remaining glass fragments will affect the next experimental test operation

At the same time, the adhesive tape is also likely to be broken by the force of the tempered glass explosion, causing the operator to be injured. Therefore, it is very necessary to improve the tempered glass fragment test device

[0004] Chinese patent application number: 2009203050079, tempered glass falling ball test bench, in order to solve the problem of glass fragments splashing everywhere when tempered glass is used for experiments, the method of supporting frame box is adopted, although it can effectively remove glass fragments, it is inconvenient to read glass fragments , and the installation efficiency of continuous multi-piece tempered glass is low

[0005] China's other patent application number: 201420595067.X, tempered glass shard state test device, proposed some new methods and measures to deal with the pressure plate of brittle glass, but it is still impossible to adjust the size at will, and it is impossible to make the four sides of the pressure plate all in the same on flat surface

At least one side of the patent must not be in contact with the test bench surface

What is referred to as the suspended retaining wall 5 in the embodiment cannot be in contact with the base 1 simultaneously with other three-sided retaining walls, so the retaining piece 4 has to be used to make up the gap between the suspended retaining wall 5 and the base 1, resulting in four Uneven surrounding force

In addition, the width of the baffle 4 itself is fixed, and only multi-piece splicing can be used, and continuous changes of different widths cannot be achieved.
